Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 26,601,631, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 26,601,631 | |
| -1 | -26,601,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,601,631.
Example:
1 x 26,601,631 = 26,601,631
and
-1 x -26,601,631 = 26,601,631
Notice both answers equal 26,601,631
With that explanation out of the way, let's continue. Next, we take the number 26,601,631 and divide it by 2:
26,601,631 ÷ 2 = 13,300,815.5
If the quotient is a whole number, then 2 and 13,300,815.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 26,601,631 | |
| -1 | -26,601,631 |
Now, we try dividing 26,601,631 by 3:
26,601,631 ÷ 3 = 8,867,210.3333
If the quotient is a whole number, then 3 and 8,867,210.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 26,601,631 | |
| -1 | -26,601,631 |
Let's try dividing by 4:
26,601,631 ÷ 4 = 6,650,407.75
If the quotient is a whole number, then 4 and 6,650,407.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 26,601,631 | |
| -1 | 26,601,631 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 271 | 379 | 1,897 | 2,653 | 10,027 | 14,023 | 70,189 | 98,161 | 102,709 | 718,963 | 3,800,233 | 26,601,631 |
| -1 | -7 | -37 | -259 | -271 | -379 | -1,897 | -2,653 | -10,027 | -14,023 | -70,189 | -98,161 | -102,709 | -718,963 | -3,800,233 | -26,601,631 |
